The Nature of Force
Two or more forces acting on one object.
What is net force?
The force that two surfaces exert on each other as they rub together.
What is friction?
What is three?
A characteristic of a moving object that is related to its mass and velocity.
What is momentum?
When the only force acting on an object is gravity, the object is said to be in.
What is free fall?
You do this when two forces act in the same direction.
What is add them together?
This law states that an object's acceleration depends on its mass and the force acting on it.
What is Newton's Second Law?
What is Conservation of Momentum?
Any force that causes an object to move in a circle.
What is centripetal force?
When to forces are acting in opposite directions, you must do this to find their net force.
What is subtract?
This type of friction occurs when a solid object moves through a fluid.
What is fluid?
This law states that if one object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction of the first.
What is Newton's Third Law?
When two objects collide and momentum is transferred from one object to the other, it's know as.
What is a "Non-Sticky" Collision?
When swinging the cup of water around in class, this kept the water from spilling out.
What is centripetal force?
When two forces act in opposite directions with equal force, their net force is equal to this.
What is 0 N?
This type of friction occurs when an object rolls across a surface.
What is rolling?
This law states that an object at rest will remain at rest and an object in motion will remain in motion until acted upon by an outside force.
What is Newton's first Law?
The formula for finding momentum.
What is momentum = mass x velocity?
Near earth's surface, the acceleration due to gravity is.
What is 9.8 m/s²?
The SI unit for force.
What is the Newton?
This type of friction acts between objects that aren't moving.
What is static?
If you run into a brick wall with a force of 20 N, how much force does the wall hit back with?
What is 20 N?
When two objects collide and momentum is shared between them, it's know as.
What is a "Sticky" Collision?
The force of gravity is responsible for continuously changing this, in which a satellite moves.
What is direction?
